[PATCH i-g-t, v5 3/7] tests/kms_colorop_helper: Add Fixed Matrix enum names table

[Swati Sharma <swati2.sharma@intel.com>]

Add kms_colorop_fixed_matrix_t enum and kms_colorop_fixed_matrix_names[]
lookup table for FIXED_MATRIX type strings, replacing raw string
literals in colorop instances.

This follows the same pattern used by kms_colorop_lut1d_tf_names[] for
1D LUT transfer functions.

Also, adds missing encoding/range to bt2020_limited instance.
